1.what is the longitude of town x whose time is 12:00 noon when Greenwich mean time is 6:00pm. 2.it The time at town A (longitude 75 degree W) 5:00pm on Friday, what will be the time and day at town B (longitude 120 degree E)

To find the longitude of a town, we need to calculate the time difference between the town and the reference point, usually the Prime Meridian (longitude 0 degrees).
1. For the longitude of town X:
Since the time at Greenwich Mean Time (GMT) is given as 6:00 PM and the time in town X is given as 12:00 noon, we need to calculate the time difference between these two points.
To determine the time difference, we subtract the GMT time from the town X time: 12:00 noon - 6:00 PM = -6 hours.
This means that the time in town X is 6 hours behind GMT.
To find the longitude corresponding to this time difference, we use the fact that each time zone generally corresponds to a 15-degree longitude difference. Since the time difference is -6 hours, we divide it by the time difference per degree (15 degrees per hour) to find the longitude difference:
-6 hours ÷ 15 degrees per hour = -0.4 degrees.
Therefore, the longitude of town X is approximately -0.4 degrees.
2. For the time and day at town B from town A:
Since the longitude of town A is given as 75 degrees West and the time in town A is 5:00 PM on Friday, we need to calculate the time and day difference between town A and town B.
To determine the time difference, we need to find the longitude difference between the two towns. Since town B is at 120 degrees East and town A is at 75 degrees West, we need to find the total longitude difference:
75 degrees West + 120 degrees East = 195 degrees.
To convert this longitude difference into a time difference, we divide it by the time difference per degree (15 degrees per hour):
195 degrees ÷ 15 degrees per hour = 13 hours.
Therefore, the time difference between town A and town B is 13 hours.
To calculate the time and day in town B, we add the time difference of 13 hours to the time in town A, which is 5:00 PM on Friday:
5:00 PM (town A) + 13 hours = 6:00 AM (next day) on Saturday (town B).
Therefore, the time and day in town B will be 6:00 AM on Saturday.
